Model.findOne() is the actual way to finding single document from database using findOne() query
whereas Query.prototype.findOne() means prototype of findOne Query
as per documentation : you can pass your filter, projection, options objects and callback function to your query
example :
Kitten.where({ color: 'white' }).findOne(function (err, kitten) {
if (err) return handleError(err);
if (kitten) {
// doc may be null if no document matched
}
});
mongoose have displayed prototypes of all Query you can use to your Model , means what you can pass to your Query while finding documents.
